http://peacecorps.mtu.edu/moringa.htm Check out this tree, the leaves are edible, the pods are edible, the bark assists digestion, the roots aid in other disorders, animals can eat it, it grows up to 4 yards per year in sandy dry acid soil. Called a 'miracle tree' in parts of the world, all parts of it are useable, even the oil in the pods can add nutrition. We bought seeds at an organization called Church World something, near Bradenton Florida, they are on the net. Even mulch is made better by it; it has more vitamens and minerals than common everyday foods in a gram by gram basis. My 5 seeds are going to be planted this afternoon. Put the name into google, the Church World something is on the first page.
